Preventing SIDS: New Advice for Parents
While the bedding may cause infants to overheat, or cause
suffocation, a physiological process called "re-breathing" may also be
at work, he says.
"Babies who get their faces in this bedding breathe their
own expired air -- carbon dioxide -- and don't get sufficient fresh air,"
Thach tells WebMD. "This gives rise to impaired respiratory function,
oxygen depletion. Some babies have not yet learned to turn their heads when
oxygen gets too low, so they may not sense that carbon dioxide is building
Most cases of SIDS occur when babies are two or three months
old, "a peak time when babies start to squirm, to pull things over their
faces, develop mobility," says Thach. "Yet they have not yet learned
how to extract themselves from these dangerous situations."
The SIDS Alliance advocates dressing babies in a light piece of
clothing called the "Dutch sleeping sack," Thach tells WebMD. The
baby's head and arms are uncovered, but the chest and rest of the body are
enclosed in a "sort of a bag," he says. "Babies have a reduced
ability to roll over [onto their stomach], reduced ability to scoot around in
the crib and get into dangerous situations."
Allowing infants to share an adult's bed has also proven to be
dangerous, causing cases of accidental suffocation, says Thach. "It appears
to occur more often when adults or siblings are in bed asleep or unconscious of
what is happening to the infant. Babies can pull covers over their heads, scoot
under comforters. In some cases, part of the adult's body -- a leg or a breast
-- covers the baby's face."
Placing babies on sofas or in overstuffed chairs is equally
risky, he adds, because a baby's head can become trapped or wedged in a tight
place or under cushions. "Even the bed frame is risky," says Thach.
